What is the best wireless mic for video cameras?

I need a Mic for making a Business Video?!?! (Help)?

• I'm going to be recording a business video for my work... I have 2 DSLRs im going to be using for video (Canon Rebel T1i & Nikon D80) I want good audio too though... Ive never used a mic before and I need a good one without breaking the bank. What should I look for when buying a mic? How will I know if its compatible to the cameras? Please any info will help me. I'm a graphic designer looking into my first video project :) Thanks
